Sales of imported tools = 25% of the total sales = 0.25*{total} = {total}/4;
Sales of Japanese tools = 45% of the sales of imported tools = 0.45*{total}/4 = 9/20*{total}/4 = 9*{total}/80.
Since the sales of of Japanese tools was x, then 9*{total}/80 = x --> {total} = 80x/9.
Answer: E.
Sales of Japanese tools = 45% of the sales of imported tools = 0.45*{total}/4 = 9/20*{total}/4 = 9*{total}/80.
